I got it partially working by placing the code in a rectangle and giving the rectangle an id of player
But I get a Warning in the console.
Warning: Unknown DOM property data-className. Did you mean data-classname?
This is in the toneden.js so I cannot fix it.
This property warning will stop the controls showing.
I can start the music by scrubbing along the track progress bar but that is not what we really want. You may want to contact the developer and ask for some advice.
Note; where is says
'<YOUR SOUNDCLOUD CONSUMER KEY HERE>'
